i have a problem when i use the httpwebrequest for a page the page is displayed correctly and when but ispostback is always false.
i m sending the viewstate data too but it is still false
how can i make it to true so that i can access the full data.
the code is as follow
static CookieContainer cookieJar = new CookieContainer();
public string PostContenct(string dataPost, string srcuri)
{
Uri uri = new Uri(srcuri);
string data = dataPost;
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(uri);
request.CookieContainer = cookieJar;
request.AllowAutoRedirect = true;
request.Method = WebRequestMethods.Http.Post;
request.ContentLength = data.Length;
request.ContentType = "application/x-www-form-urlencoded";
StreamWriter writer = new StreamWriter(request.GetRequestStream());
writer.Write(data);
writer.Close();
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
int cookiecount = cookieJar.Count;
StreamReader reader = new StreamReader(response.GetResponseStream());
string str = response.StatusDescription;
string tmp = reader.ReadToEnd();
response.Close();
return tmp;
}
thanks

I have a variable
byte[] rxData;
And VS is complaining that it is unassigned. However i dont want to assign it as this is done in the switch statement that follows.
does anyone know why it still complains
;switch (rxMessage[3])
{
case 0x46:
for (int i = 4; i <= 1028; i++)
{rxData[i - 4] = rxMessage[i];}
break;
case 0x42:
rxData[0] = 0;
break;
case 0x4f:
rxData[0] = rxMessage[4];
break;
case 0x43:
rxData[0] = rxMessage[4];
break;
default:
throw new InvalidDataException("Error: Incorrect Subcommand type may have been found");
}

Hi,
maybe you have to initialise rxData first. It is set to null by default, but to assign values to the array (using an index like 0 at nul won't work). It must be initialised like this:
byte[] rxData = new byte[1024];
Regards

You have not defined the array.
byte[] rxData = new byte[someNumber];
|
|
|
|
|
Thanx For both of your answers this does allow the code to compile.
Was just hoping i could declaire it and give it a value in the switch without it complaining. The flow was being forced through the switch so though it would work.
Thanx for your time

No, it wouldn't work: that is the whole point.
To cut down your code a little:
byte[] rxData;
rxData[0] = rxMessage[4];
You would still get your compile error, since rxData is null, thus rxData[0] does not exist. This is why the compiler complains.
byte[] rxData = new byte[1024];
rxData[0] = rxMessage[4];
Is fine, since rxData is no longer null, and rxData[0] (through rxData[1023]) exists and can be assigned.

Here is exactly what you want: [^].
The provided source code uses avicap32.dll, so if you want a WIA solution check this article: [^].
I hope these links help you,

I don't understand that.
The source code from the second link uses exactly the PictureBox control to show the captured video (picture by picture using timer). Please check out the provided source code for the article. The are 2 versions of the code available (for C# and VB). You can use the provided technique and place the PictureBox wherever you want.
Best wishes!

I also have the server error for the first article. 
But i have downloaded and tested the source from the second one. It uses exactly the WIA, the PictureBox control and it is working!

Bloody hell. You've been given explicit instructions, day after day. Perhaps you should just abandon this project ?

Hi rakesh312,
#1. Add a reference to your project point to \windows\system32\wmp.dll
#2. add this one in top of code :
using WMPLib;
#3 to get media player version is something like this :
WindowsMediaPlayer wmp = new WindowsMediaPlayer();
MessageBox.Show( wmp.versionInfo.ToString());
Good luck
